Title:
  do-release-update crashes on lines 126-127

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

Bug description:
  When I tried to upgrade my Xubuntu 14.10 to Xubuntu 15.04, I got a
  message:

  -------------------------------------------------------------------------------------------------
  Проверка наличия нового релиза Ubuntu
  Ваша версия  Ubuntu больше не поддерживается.
  Traceback (most recent call last):
    File "/usr/bin/do-release-upgrade", line 127, in <module>
      "%(url)s\n") % { 'url' : url })
  ValueError: unsupported format character '?' (0xa) at index 55
  -------------------------------------------------------------------------------------------------

  Then I searched through the internet and solved this problem. The
  solution for me was to edit with "gedit" file "/usr/bin/do-release-
  upgrade" and change lines 126 and 127:

  From
  ----------------------------------------------------------------------------
  print(_("For upgrade information, please visit:\n"
  	"%(url)s\n") % { 'url' : url })
  ----------------------------------------------------------------------------

  To
  ------------------------------------------------------------------------------------------------------------------
  print(_("For upgrade information, please visit:\n %(url)s\n") % { 'url' : url })
  ------------------------------------------------------------------------------------------------------------------

  And after that, do-release-upgrade successfully started upgrading
  Xubuntu.
